- the materials constituting the thermoelements are joined by a conductive material whose thermoelectric power is assumed to be zero.
- the two branches (p and n) of the thermocouple and all the thermo couples forming the module are, on the one hand, electrically connected in series and, on the other hand, thermally parallel.

- Due to the low efficiency of thermoelectric materials and the complex shaping of thermo-generators, energy recovery solutions are inefficient, expensive and difficult to implement. In the field of low temperature gradients with ambient temperature, two cases may occur:
- thermoelectric cooling To dissipate the thermal energy by thermoelectric cooling, more reliable system than the fans, to protect a device, it is for example the case of the electronic components;
- thermoelectric modules based on Bi 2 e 3 in particular, are generally of small surface, a few square centimeters at most.
- thermo-generators including thermoelements and their connections are inserted between supports which are generally alumina, silicon or other type. These supports provide the mechanical rigidity of the assembly. Thermoelements electrically interconnected between these supports are surrounded by air or, in some cases, by thermal insulating materials avoiding possible corrosion.

- the plate 18 has this plurality of first holes 20a and second holes 20b which are arranged by being preferably distributed homogeneously and alternately first holes 20a with the second holes 20b. It is thus understood that between two first holes 20a is preferably a second hole 20b.
- an amount of p-type thermoelectric powder 22 and an amount of n-type thermoelectric powder 24 are then fed.
- a first layer of these powders is available, for example a p-type powder layer 22 on which the plate 18 is just disposed, and then the n-type powder 24 is placed on top of the plate 18.
- the second face 18b of the plate 18 is placed on a p-type powder layer 22, and then a layer of n-type powder 24 is placed on the first face 18a of the plate 18. It is understood that it would be possible to invert the arrangement of the faces and put the first face 18a on the p-type powder layer 22 and cover the second face 18b with a n-type powder layer 24. Similarly, it is also possible to invert and first put a layer of n-type powder 24, then come to deposit the plate 18, which is then covered with a p-type powder layer 22.
- step (c) of FIG. 2B pressure is then applied to these p- and n-type layers so that the powder enters the respective holes.
- a pressure P is applied to each of the layers, so that the p-type powder 22 enters the second holes 20b and the n-type powder 24 enters the first holes 20a.
- a pressure P of the same value is applied preferably on both sides of the plate 18; this uni-axial pressure allows the powder to penetrate properly into the non-through holes by filling them and this symmetrically between the first face 18a and the second face 18b.
- the plate 18 has a thickness el8, the first non-through holes 20a have a depth e20a and the second holes 20b have a depth e20b.

On the contrary, this total duration D can be increased up to 60 minutes if the temperature T is higher or in the case of a conventional sintering type HUP or HIP.
- thermo-generator 10 as described above, can therefore be of a fairly large size up to several hundred millimeters in diameter.
